This does not mean everyone should go vegetariam, even reducing meat intake could have envrionemntal and health benefits.

Consuming a plant-based diet results in a more sustainable environment and reduces greenhouse gas emissions, while improving longevity, according to new research. Based on findings that identified food systems as a significant contributor to global warming, the study focuses on the dietary patterns of vegetarians, semi-vegetarians and non-vegetarians to quantify and compare greenhouse gas emissions, as well as assess total mortality.
